 No, but I've seen a similar one which was due to the fact that GDK (used by
GTK+ used by wxGTK used by wxPython) changes the current locale by itself.
And if in the new locale the decimal separator symbol is not period any more
this might cause problems (although I still fail to see how can this lead to
the result above to be honest).

 To check if this guess is correct, just unset LANG and all LC_XXX environment
variables and repeat the test above.

 If the problem is due to this, just do "LANG=C python" instead of just
"python" (assuming you use a ksh-derived shell).
